pmean.m v1.1 (Sep 2009)
This function calculates the mean and standard deviation of vectors in polar coordinates (and others), that is, from angles and magnitudes.
The usage is very simple:
For polar or cylindrical: Direction, Radius, Height
[mD,eD] = pmean(D);
[mD,mR,eD,eR] = pmean(D,R);
[mD,mR,mH,eD,eR,eH] = pmean(D,R,H);
For spherical coordinates: Azimuth, Elevation, Radius
[mA,eA] = pmean(A);
[mA,mE,eA,eE] = pmean(A,E,'s');
[mA,mE,mR,eA,eE,eR] = pmean(A,E,R,'s');
For cartesian coordinates:
[mX,eX] = pmean(X,'c');
[mX,mY,eX,eY] = pmean(X,Y,'c');
[mX,mY,mZ,eX,eY,eZ] = pmean(X,Y,Z,'c');
where "m" stands for MEAN's, and "e" for STD's.
Input angles should be in radians.
It ignores NaN's.
Enjoy it!
Any comments or bug reports will be very appreciated!
